Oyama Masutatsu as well. Born in Korea, emigrated to Japan, trained to be a Kamikaze pilot, war ended before he could an hero for his colonial overlords, and in the aftermath decided that he hated everything Korean and became a full-time Jap.
His chosen occupation still meant that he got to beat up Japs, though, so he still did his duty to the old motherland.
Korean proto-weebs have been a thing since Japan annexed the country in 1910, and it never really went away.
Taiwan is a similar story, actually, and Japan flat-out granted everyone on the island Japanese citizenship in early '45 in a bid to keep the island after the impending American victory. The Japanese were generally well-liked by the Chinese population there, too, primarily because the Japs massacred the native tribes that previously caused trouble for the Chinese colonists.
America did of course go 'lolno, this is now Chinese clay'.
We're still paying for this mistake today.
